These SPG21, maspardin ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. SPG21, maspardin is an alias of the human SPG21 gene, which encodes the protein, SPG21 abhydrolase domain containing, maspardin. The protein is believed to play a role as a negative regulatory factor in CD4-dependent T-cell activation. The SPG21 protein is 308 amino acid residues in length and 35 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the membrane, golgi, and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in all tissues tested, including heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas. Other names for this target antigen include ABHD21, ACP33, and BM-019. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
